How do I create an alert if a user's email address or passwords are invalid?

You don't need to take care of these alert dialogs. FlutterFlow automatically shows the error messages generated in a SnackBar widget.

I get this error: The operation couldn’t be completed. Unable to locate a Java Runtime. Please visit for information on installing Java.

You will need to install Java Runtime on your machine. Please visit and download Java based on your OS.
